Nancy.Owin vs Nancy.Hosting.Self with topshelf - owin

Question

1) What is the differences between setting up with the two different packages? Is one more supported than the other?
I had a project using Nancy.Hosting.Self and didn't find any article about how to setup windows authentication, while I did find it for Nancy.Owin as middleware. I have now switched to Nancy.owin.
Here are a few different questions.
2) The jsonformatter can be configured in both the nancy bootstrapper as in the owin endpoint topshelf.
Where should I configure the formatter? If configured in the topshelf owin endpoint, will this be applied in the nancy bootstrapper as well?
3) With the nancy endpoint in topshelf there was an option to set firewall rules and url reservations. I can't find this in the owin endpoint.
private static void CreateHost(HostConfigurator host)
{
var logger = SetupLogging();
host.UseSerilog(logger);
host.UseLinuxIfAvailable();
//sc => serviceconfigurator, ls => licenseService
host.Service<WebService>(sc =>
{
sc.ConstructUsing(name => new WebService(_config));
sc.WhenStarted(ls => ls.Start());
sc.WhenStopped(ls => ls.Stop());
sc.OwinEndpoint(app =>
{
app.ConfigureHttp(configuration =>
{
//use json.net serializer
configuration.Formatters.Clear();
configuration.Formatters.Add(new JsonMediaTypeFormatter());
//configure json settings
var jsonSettings = configuration.Formatters.JsonFormatter.SerializerSettings;
jsonSettings.Formatting = Formatting.Indented;
jsonSettings.Converters.Add(new StringEnumConverter { CamelCaseText = false, AllowIntegerValues = true });
jsonSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
});
app.ConfigureAppBuilder(builder =>
{
builder.UseNancy(options =>
{
options.Bootstrapper = new Bootstrapper(_config);
//options.PerformPassThrough
});
});
app.ConfigureStartOptions(options =>
{
options.Port = _config.LicenseServicePort;
//options.Urls = new List<string>(){};
});
});
//add host reservation during service install, this is the only time, nancy will have admin rights, will be deleted when service is uninstalled as well.
//nc => nancyConfig
//sc.WithNancyEndpoint(host, nc =>
//{
// nc.AddHost(port: _config.LicenseServicePort);
// nc.CreateUrlReservationsOnInstall();
// nc.DeleteReservationsOnUnInstall();
// nc.OpenFirewallPortsOnInstall(firewallRuleName: "mycustomservice");
// nc.Bootstrapper = new Bootstrapper(_config);
//});
});
host.SetDescription("Licensing service for my api.");
host.SetDisplayName("myservice");
host.SetServiceName("myservice);
host.RunAsNetworkService();
host.StartAutomatically();
}
